Developments with hormonal contraceptives for elephants

Abstract

Only a summary of the presentation was published. Outlines the ongoing research into the use of hormonal contraceptive initiated to develop as an alternative to culling. The research includes the study of biochemical correlates, interactions between steriods and receptors, and the techniques to interfere with the receptor mechanisms. A receptor for progesterone in the elephant has been identified, and norethindrone and levornorgestral show some potential as anti-progesterones.
